Ssemakula Peter Luyima provides a new concept for World Economy in the 21st century, by producing a revised concept of MuRatopian Economy; 30 years after Professor Kaoru Yamaguchi presented a synthesized analysis of the Neoclassical, Keynesian and Marxian with his own public money economic model. It is this author’s intention not only to provide an integrative concept for reconstruction of the World Economy, but to present an equitable economic strategy in the context of Louis Orth Kelso’s important two factor economics at the same time. This book is an introduction to a new upcoming theory MuRatopian Intersection Economy.
